SAFETY DEVICE FOR RAILWAY-CARS.

SPECIFICATION forming part of Letters Patent No. 416,152, dated December 3, 1889.

Application filed August 9, 1889.

To all whom it nut/y concern Be it known that I, ALEXANDER A. CAM- ERON, a citizen of the United States, residing atUobbville, in the county of Telfair and State of Georgia, have invented a new and useful Safety Device for Railroad-Oars, of which the following is a specification.

This invention has relation to devices for the prevention of railroad-cars from leaving the tracks; and the invention consists in certain features of construction hereinafter specified, and particularly pointed out in the claims.

Referring to the drawings, Figure 1 is a side elevation of a car provided with my invention. Fig. 2 is an end elevation thereof; Fig. 3, a detail in perspective of the safetyframe.

Like numerals of reference indicate like parts in all the figures of the drawings.

In practicing my invention I prefer to mount the safety device at both ends of the car, though, if desired, I may employ several intermediate the ends. In this instance, however, I have shown the same applied to the ends of each platform.

1 represents the platform of a car, from the opposite corner of each of which there depend hangers 2, securely bolted to the plat form bybolts 3, and terminating at theirlower ends in threaded studs 4.

5 represents a rectangular frame, and consists of an upper and lower bar 6 and 7 and opposite side bars 8 and 9, the four comprising a frame of a length reaching nearly to the track. The upper bar 6 is provided with slots 10, arranged longitudinally with relation to the frame and near each end thereof, said slots receiving the threaded stud l of the hangers 2, and being loosely connected with the studs by means of nuts 11, threaded on the studs and against the under face of the bar 6. Opposite recesses 12 are formed in the side bars 8 and 9, near their upper portions, and in said bars terminate the opposite ends of an intermediate transverse bar 13.

Intermediate the slots 10 and the upper bar 6 are formed a pair of bearings 15, which register with a similar pair of bearings 15, formed in both the intermediate transverse bar 13 and the lower transverse bar 7. Within these bearings are j ournaled vertical rods 16,

which are provided with threads and with nuts 17, which embrace the bars 6 and 13 at through the lower transverse bar 7 and terminate in loose heads 19, the contour of which adapts them to conform to the head and web of the usual track-rails 20, and the heads 19 of the rods 16 interlock under the head of the rails and loosely connect the car therewith, thereby preventing a raising of the car-wheels from their rails, and thus the ear is prevented from jumping the track. The swaying motion of the coaches is permitted by reason of the. elongated slot 10, and the device herein described will not prevent an easy rounding of curves or the resiliency of the car-springs in any manner.

Any desired form of bracing for theframe 5 may be employed, and I herein show opposite braces 22, the upper ends of which are bolted to the under side of the car or platform, as at 23, and their lower ends bent, as at 24, and bolted to the under face of the lower bar 7, as at 25.

The lower transverse bar of the frame is preferably provided between the depending rods with an intermediate bearing 26, and upon the same is loosely mounted a supplemental wheel 27, that runs upon the surface of the intermediate rail or track-iron and serves to prevent the revolving head from coming in contact with the cross-ties of the road.

I-Iaving described my invention, what I claim is.

1. The combination, with a car and. rail, of a frame loosely connected to the car and provided with opposite rods depending from the frame and terminating in heads embracing the rail, substantially as specified.

2. The combination, with a car and a rail, of a frame depending from the car and loosely connected therewith, and vertical parallel rods terminating in rotatable heads fitting specified.

3. The combination,witha car and rails, of hangers depending from opposite sides of the car and terminating in threaded studs, a rectangular frame having slots in its upper end to receive the studs, and nuts mounted on the opposite sides of their bearings 15 and support the rods in position. The rods 16 pass under the head of the rail, substantially as- ICYO studs for the retention of the frame, and a pair of rods mounted in the frame in vertical bearings and terminating in rotatable heads fitting at either side of the supplemental rail and against withdrawal in a vertical direction therefrom, substantially as specified.

4. The combination, with a car and rails, of opposite hangers bolted to the car and terminating in threaded studs, a rectangular frame provided with opposite slots for the reception of the studs, nuts mounted on the studs for the retention of the frame, a transverse bar mounted in the frame, bearings formed in the upper and lower bar of the frame and the transverse bar, all in vertical line with each other, and a pair of threaded rods having journals for the bearings and depending below the frame and terminating in rotatable heads conforming to the shape of the head and Web of the rails, and provided with opposite nuts embracing the sides of its bearings, and rear vertical braces secured to the body of the car and extending forwardly and bolted to the lower transverse rail of the frame, substantially as specified.

5. The combination, with opposite rods terminating in heads, their supporting-frame, and rail embraced by the heads, of a bearing located between the rods, and a loose wheel journaled upon the same and bearing'on the rail, substantially as specified.

6. The combination, with the rectangular frame having the hearing at its center and formed upon the lower transverse bar thereof, of the opposite depending rods mounted in the frame and provided with revolving heads, and a rail embraced by the heads and supporting the wheel, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto ailixed my signature in presence of two witnesses.

ALEXANDER A. CAMERON.
